Canon ET-73C Lens Hood for RF 100mm f/2.8L Macro IS USM Lens

The ET-73C Lens Hood from Canon is designed for the RF 100mm f/2.8L Macro IS USM Lens and prevents unwanted stray light from entering the lens. It extends the shading at the end of the lens and minimizes ghosting and flare when shooting in strong lighting conditions. Additionally, since the end of the lens is extended, you also get the added benefit of extra protection from bumps and impacts.
